[NU Sports] PSU and how this could have been so easily avoided..

[Dennis W. Brandt]

Dennis, you miss my point and I apologize if I wasn't specific. The school teacher in your example, would never have to go to the Principal. She reports directly to DCFS. DCFS then goes to the principal and says "a report has been made". 

It was a lot points that I was not missing.  And what you say is not true in Pennsylvania.  Here is the law.  I added the bold font.

Staff members of institutions, etc.--Whenever a person is required to
report under subsection (b) in the capacity as a member of the staff of a
medical or other public or private institution, school, facility or agency,
that person shall immediately notify the person in charge of the institution,
school, facility or agency or the designated agent of the person in charge.
Upon notification, the person in charge or the designated agent, if any, shall
assume the responsibility and have the legal obligation to report or cause a
report to be made in accordance with section 6313. This chapter does not
require more than one report from any such institution, school, facility or
agency.

You tell the principal, not the cops.  If the principal is the one whom you suspect is guilty of abuse, you tell his or her boss.  The law is clear.

I also found this.

A person, hospital, institution, school, facility, agency or
agency employee that participates in good faith in the making
of a report . . . shall have immunity from civil and criminal liability that
might otherwise result by reason of those actions.

So, my wife is safe from prosecution, but that doesn't mean that she is safe from retaliation from the school if she were to go over the administration's head.
